10. FINAL ChECk

A. If your vehicle has gone over 15,000 miles

since its last spark plug change, you will need

to change the spark plugs now before test

driving the vehicle.

B. Check all fitting, nuts, bolts and clamps for

tightness. Pay particular attention to oil and

fuel lines around moving parts, sharp edges

and exhaust system parts. Make sure all

wires and lines are properly secured with

clamps or tie-wraps.

C. Check all fluid levels, making sure that your

tank(s) is/are filled with 91 octane or higher

fuel before commencing test drive.

D. (For Internally Lubricated V-3 Units Only)

This supercharger has been factory pre-filled

with special Vortech synthetic lubricant. Oil

does not need to be added to a brand new

unit; however a fluid level check should be

performed.

Prior to operating the supercharger on the

vehicle and after installation onto the vehicle:

Remove the factory installed flat-head brass

shipping plug (not the dipstick) from the top

of the supercharger case. Replace the sealed

shipping plug with the supplied “vented” plug.

Do not operate the supercharger without it.

Check the supercharger fluid level.

Fluid level checking procedure:
1. Ensure that the .06” copper sealing

washer is located on the dipstick base.

2. Thread the clean dipstick into the super-

charger unit it seats.

3. Once the dipstick has seated, remove

the dipstick from the unit. Fluid should

dipstick.

4. DO NOT OVERFILL!!! Drain excess fluid

the unit if it is above the maximum level

on the dipstick.

NOTE:

Once the Re-flashed ECU and TCM are received back from Vortech, reinstall them in the reverse order removed.

Take care not to damage the harness connectors or ECU/TCM connection pins. Re-secure the washer fluid/cool-

ant reservoir assembly.

WARNING: Do not attempt to operate the vehicle

until all components are installed and

all operations are completed including

the final check.
